python - 官方文档 笔记(1) 查看文档 官方中文文档pdf下载

链接: https://pan.baidu.com/s/1KB_r9OxODpB_DEmWciQLKg 提取码: e5df
hellow3 一个奇怪的python doc网站

推荐使用有道词典，能很正确的解释函数的用法，甚至英文翻译

笔记中大多环境是ipython：python - ipython 安装到使用

楼难爬，难得下载了中文pdf，这里记一下心得！

1、内置函数

dir()简略查看函数信息 print()
help()详细查看函数信息
list.__doc__ 查看函数list的简介 print()

以下方法可以看到内置函数：__builtins__

注意用help的话，可以说一次性看到所有内置函数的文档，因为太长，无法在博客上发布，于是大家自己看吧！

因为__builtins__是一个特定参数，而非一个函数的集合，所以无法使用__builtins__.__doc__查看到信息
函数使用方法，既然可以一次性看到函数的方法，之后大家help(函数)就是。
